Counting Principles

In statistics, the counting principle can be said to be the concept in which the quantity of an item is determined. There can be a single item, or a group of items, or items that are related to each other. In every possible set of items, the quantity of the possible item groups or their sorting measures can be determined with counting principles.

The average yield of soybeans in Ohio is 58 bu/Acre (the control mean). We wish to test whether a field that has been treated with the product has soybean yields that are different than 58 bu/acre. We are going to conduct a study with 49 fields and set up the hypothesis at α=.05. After we conduct the experiment we get a sample mean x = 60 bu/Acre and s=7 bu/acre. Conduct the test.

The overall distance traveled by a golf ball is tested by hitting the ball with Iron Byron, a mechanical golfer with a swing that is said to emulate the distance hit by the legendary champion Byron Nelson. Ten randomly selected balls of two different brands are tested and the overall distance measured. The summary statistics are ∑X1i=2764, ∑X21i=764410, n1=10. ∑X2i=2636, ∑X22i=696144, n2=10. Assume normality and that the two samples have the same variance. Test the hypothesis that both brands of ball have equal mean overall distance. 1a. What is the P-value? 1b. Let α=0.05, are you going to reject the null hypothesis?

Travis does research with a marine biology research team. His job is to catch lobsters, weigh them, tag them, and return them to the water. Over the years, the team has determined that the average weight in pounds of the lobsters caught at a particular location was µ = 2.1 lbs. with a σ of 1.8 lbs. As part of an annual survey, Travis catches 27 lobsters with a mean of 3.1 lbs. Is he correct in assuming that the lobsters he caught are significantly heavier that those usually found in that location? Please use α = .05 and a two-tailed test.
International public health practitioners have continuously attempted to point out differences in smoking rates across the globe.Some say that smoking rates do not match up with disease outcomes, i.e.,countries that have the highest rates of smoking do not have the highest rates of outcomes like lung and esophageal cancers. Suppose that a new research team wants to observe the difference in average smoking rates between Americans and French smokers. In order to test the assumption that French smokers smoke less on the average than Americans, the researcher takes a SRS of smokers from each country and compares their basic descriptive statistics for number of cigarettes smoked per day. Assume the following table summarizes the findings. Country Average cigarettes smoked per day Standard deviation Sample size France 8.9 1.4 52 USA 8.7 3.1 46 A) Carry out the appropriate test to answer the research question that supposes that American smokers smoke more cigarettes per day on the…
Workers in the office like to drink coffee during work. A doctor is concerned about this situation since the too much coffee consumption may result to long-term health problems. However, studies suggests that there is no risk in drinking three cups of coffee per day, which is about 250 mg of caffeine. The doctor wants to know if the amount of caffeine consumed by the workers is within tolerable limits. He randomly selected 20 students and found that they consume an average of 270 mg of caffeine each day with a standard deviation of 48 mg. Assume that the daily amount of caffeine consumed by students follow the normal distribution.1. Which of the following sets of hypotheses should be used in this study? A. Ho: μ = 250 vs. Ha: μ > 250 B. Ho: μ ≤ 250 vs. Ha: μ > 250 C. Ho: μ = 270 vs. Ha: μ > 270 D. Ho: μ = 270 vs. Ha: μ ≠ 270 2. Which of the following is(are) TRUE? I. The appropriate test procedure to answer the objective of the study is a…
